Your MRR is climbing but you can’t cover next month’s bills. That disconnect is exactly what the quick ratio exposes. It’s the fastest way to check whether your business can actually pay what it owes, right now, without selling inventory or praying for future revenue.
Quick Ratio = (Cash + Short-Term Investments + Accounts Receivable) / Current LiabilitiesIf the result is above 1.0, you can cover your short-term obligations with liquid assets alone. Below 1.0, you have a problem that no amount of MRR growth will fix fast enough.
SaaS Quick Ratio: Formula, Benchmarks, and How to Use It
Quick ratio is a liquidity metric that measures whether a company can pay off its current liabilities using only its most liquid assets, cash, short-term investments, and accounts receivable. It excludes inventory and prepaid expenses because those can’t be converted to cash overnight.
For SaaS founders, this ratio answers a blunt question: if all your bills came due tomorrow, could you pay them without borrowing or liquidating something illiquid?
A profitable SaaS on paper can still run into cash crunches, especially with annual billing cycles where revenue arrives upfront but expenses are monthly. It doesn’t care about your ARR trajectory. It looks at what you have versus what you owe, right now.
The Quick Ratio Formula
The standard formula:
Quick Ratio = (Cash + Short-Term Investments + Accounts Receivable) / Current LiabilitiesThere’s also a simplified version that starts from current assets:
Quick Ratio = (Current Assets - Inventory - Prepaid Expenses) / Current LiabilitiesBoth arrive at the same number. The simplified version is useful if your accounting software gives you a current assets total but doesn’t break out liquid components separately.
Worked example: Say your SaaS has €45,000 in cash, €5,000 in short-term investments, and €12,000 in outstanding invoices from annual customers. Your current liabilities (hosting, salaries due, software subscriptions, taxes payable) total €40,000.
Quick Ratio = (€45,000 + €5,000 + €12,000) / €40,000 = 1.55A 1.55 quick ratio means you have €1.55 in liquid assets for every €1.00 you owe in the short term. Comfortable, but not extravagant.
Acid Test Ratio: Same Thing, Different Name
The acid test ratio is identical to the quick ratio. Same formula, same inputs, same output. The name comes from the gold-mining era, acid was used to test whether metal was real gold. The acid test ratio “tests” whether a company’s liquidity is real or padded with illiquid assets.
You’ll see both terms in financial textbooks, investor memos, and accounting software. If someone asks for your acid test ratio, hand them the same number — both labels point to identical math.
The acid test ratio formula is also identical:
Acid Test Ratio = (Cash + Short-Term Investments + Accounts Receivable) / Current LiabilitiesDon’t overthink the naming. The distinction doesn’t exist.
How to Find Quick Ratio: Step-by-Step
Step 1. Gather your liquid assets. Pull your bank balance, any money market or short-term investment accounts, and your outstanding accounts receivable. For SaaS, AR typically includes unpaid invoices from customers on net-30 or net-60 terms.
Step 2. Total your current liabilities. This includes anything due within 12 months: hosting bills, payroll, software subscriptions, credit card balances, tax obligations, and any short-term debt.
Step 3. Divide. Liquid assets divided by current liabilities. That’s the result.
Step 4. Interpret. Above 1.0 means you can cover obligations. Between 1.0 and 1.5 is adequate. Above 1.5 gives you breathing room. Below 1.0 means you need to act, either increase collections, cut spending, or secure a credit line.
If you’re building a financial model for your SaaS, the quick ratio should be one of the monthly checks you include alongside runway and burn rate.
Quick Ratio vs Current Ratio
Both ratios measure liquidity. The difference is what they count as assets.
| Quick Ratio | Current Ratio | |
|---|---|---|
| Formula | (Cash + Investments + AR) / Current Liabilities | Current Assets / Current Liabilities |
| Includes inventory | No | Yes |
| Includes prepaid expenses | No | Yes |
| Strictness | More conservative | More lenient |
| Best for | Short-term solvency check | Overall working capital health |
| Typical “good” value | >1.0 | >1.5 |
For a traditional retail business with warehouses full of product, the gap between these two ratios can be massive. For most SaaS companies, the difference is smaller because software businesses carry minimal inventory. But prepaid expenses can still create a gap, if you’ve prepaid €20,000 in annual software licenses, that shows up in your current ratio but not your quick ratio.
When investors or accountants look at financial ratio benchmarks, they typically want both ratios. The quick ratio tells the sharper story.
What Is a Good Quick Ratio?
Benchmarks vary by industry, but general guidelines hold:
| Quick Ratio | Interpretation |
|---|---|
| <0.5 | Serious liquidity risk, immediate action needed |
| 0.5–1.0 | Tight, monitor weekly, build a cash buffer |
| 1.0–1.5 | Adequate, you can cover obligations comfortably |
| 1.5–2.5 | Healthy, standard target for growing SaaS |
| >2.5 | Very liquid, possibly holding too much idle cash |
According to NYU Stern’s financial ratio data (2025), the average quick ratio for software companies is approximately 1.8. SaaS companies with strong annual prepayment models often sit between 1.5 and 2.5 because customer cash arrives before expenses are incurred.
A ratio above 2.5 isn’t necessarily better. It might mean you’re sitting on cash that could be deployed, hiring, marketing, product development. The goal is adequate liquidity, not maximum liquidity.
For bootstrapped founders specifically, a quick ratio between 1.2 and 2.0 is a practical target. Enough buffer to absorb a bad month without hoarding cash you could invest in growth.
SaaS Context: When Quick Ratio Matters Most
Most SaaS founders don’t need to check their quick ratio daily. It’s not an operating metric like MRR or churn. But there are specific moments when it becomes critical.
Before hiring. Adding a full-time team member is your single biggest fixed cost increase. Run the quick ratio to confirm you can absorb the new salary for at least 6 months without dipping below 1.0.
During annual billing transitions. If you’re shifting customers from monthly to annual plans, you’ll see a temporary cash spike followed by months of expenses without corresponding revenue inflows. The quick ratio reveals whether you can sustain the gap.
When evaluating profitability metrics. The quick ratio pairs well with EBIT vs EBITDA analysis. A business can be EBITDA-positive and still have a quick ratio below 1.0 if cash is locked up in receivables or prepaid costs.
Before taking on debt. Lenders check the quick ratio. If it’s below 1.0, expect pushback or worse terms.
The quick ratio isn’t a metric you optimize. It’s a guardrail. Check it monthly, flag it when it drops below 1.2, and investigate when it does.
FAQ
What is the quick ratio formula?
The quick ratio formula is (Cash + Short-Term Investments + Accounts Receivable) divided by Current Liabilities. It measures whether a business can pay its short-term debts using only liquid assets, excluding inventory and prepaid expenses.
What is the difference between quick ratio and current ratio?
The current ratio includes all current assets (including inventory and prepaid expenses), while the quick ratio excludes those illiquid items. For SaaS companies, the difference is usually small because software businesses carry little inventory, but prepaid costs can still create a gap between the two numbers.
What is a good quick ratio for a SaaS company?
A quick ratio between 1.2 and 2.0 is healthy for most SaaS companies. Below 1.0 signals liquidity risk, you can’t cover short-term obligations with liquid assets alone. Above 2.5 may indicate excess idle cash that could be deployed toward growth.
Why is the quick ratio also called the acid test ratio?
The name comes from a 19th-century gold-mining practice where nitric acid was used to test whether a metal sample was genuine gold — hence the acid test nickname attached to the quick ratio. The acid test “tests” whether a company’s ability to pay its debts is genuine, backed by real liquid assets rather than inflated by inventory or prepaid items, which is exactly what the quick ratio measures.
How often should a SaaS founder check the quick ratio?
Monthly is sufficient for most bootstrapped SaaS founders. Check the quick ratio more frequently during major spending events, hiring, annual billing transitions, or large marketing pushes, and always before taking on debt or making significant financial commitments.
What is a good SaaS Quick Ratio?
A Quick Ratio above 4 is excellent, it means you add $4 in new and expansion MRR for every $1 lost to churn and contraction. Above 2 is healthy. Below 1 means your business is shrinking. For bootstrapped SaaS, aim for 2-4 in the growth phase. The ratio naturally decreases as your revenue base grows because the denominator (churn) grows with your customer count.
How is SaaS Quick Ratio different from accounting quick ratio?
Completely different metrics that share a name. The accounting quick ratio measures short-term liquidity (current assets minus inventory divided by current liabilities). The SaaS Quick Ratio measures revenue efficiency: (new MRR + Expansion MRR) divided by (Churned MRR + Contraction MRR). They answer different questions, liquidity vs growth efficiency.
How can I improve my Quick Ratio?
Two approaches: increase the numerator (more new and expansion MRR) or decrease the denominator (less churn and contraction). Reducing churn is usually faster and cheaper than acquiring new customers. Improving retention rate by even 5% can significantly boost your Quick Ratio because it compounds month over month.
